Which characteristic describes DDR3 SDRAM?

• chips that run at clock speeds of 800 MHz and have a connector with 240 pins

• an individual memory chip that has dual rows of pins used to attach it to the motherboard

• a small circuit board that holds several memory chips and has a 30- or 72-pin configuration

• chips specifically designed for video graphics that are used in conjunction with a dedicated GPU

Which characteristic describes ECC memory?

• chips that can detect multiple bit errors and correct single bit errors in memory

• chips specifically designed for video graphics that are used in conjunction with a dedicated GPU

• an individual memory chip that has dual rows of pins used to attach it to the motherboard

• chips that run at clock speeds of 800 MHz and have a connector with 240 pins

Which characteristic describes GDDR SDRAM?

• chips specifically designed for video graphics that are used in conjunction with a dedicated GPU

• chips that require constant power to function and are often used for cache memory

• chips that run at clock speeds of 800 MHz and have a connector with 240 pins

• hips whose contents can be “flashed” for deletion and are often used to store BIOS

Which characteristic describes ROM?

• a chip that cannot be erased or rewritten and is now obsolete

• chips that run at clock speeds of 800 MHz and have a connector with 240 pins

• hips specifically designed for video graphics that are used in conjunction with a dedicated GPU

• chips that require constant power to function and are often used for cache memory

Which characteristic describes a DIP?

• an individual memory chip that has dual rows of pins used to attach it to the motherboard

• chips that require constant power to function and are often used for cache memory

• chips that run at clock speeds of 800 MHz and have a connector with 240 pins

• chips whose contents can be “flashed” for deletion and are often used to store BIOS

Which characteristic describes PROM?

• chips that are manufactured blank and then can be programmed once by a PROM programmer

• chips that run at clock speeds of 800 MHz and have a connector with 240 pins

• chips specifically designed for video graphics that are used in conjunction with a dedicated GPU

• chips that require constant power to function and are often used for cache memory

Which characteristic describes a SIMM?

• a small circuit board that holds several memory chips and has a 30- or 72-pin configuration

• chips that require constant power to function and are often used for cache memory

• chips that run at clock speeds of 800 MHz and have a connector with 240 pins

• chips whose contents can be “flashed” for deletion and are often used to store BIOS

Which characteristic describes EPROM?

• a chip that is nonvolatile and can be erased by exposing it to strong ultraviolet light

• SRAM that is internal and integrated into the CPU

• a smaller, more condensed memory module that provides random access data storage, ideal for use in laptops, printers, and other devices where conserving space is desirable

• a small circuit board that holds several memory chips and has a 30- or 72-pin configuration
